If you've been on a boat in San Francisco Bay, you've already seen (and drooled over) the façade of 27 Bellevue Ave. on Corinthian Island, a strip of land that juts out from Tiburon into the bay.

Now, you can see inside.

The home

The facade of this home--with its unusual blue hue, wood accents, rows of windows, and private dock--distinguishes it, even here on a shore of Corinthian Island, where the Portofino-meets-San Francisco effect promises one spectacular home after another.

Glimpsed first on the FrontSteps.com, this three-bedroom, four-bathroom custom abode seems to float on the water, and inside that nautical theme continues.

Indeed, the home "was originally custom designed in 2009 for a well-known inventor and yacht racer, and then extensively remodeled in 2015 by another tech titan, also known in international yacht racing circles," says the official listing.

Off the living room wraps a deck styled like that of an uber-luxe yacht, hugging the home and offering an unobstructed Bay view.

In the 4,205 square feet and multiple levels (all served by an elevator), there are almost too many stunning features to list, but we'll try: a chef's kitchen; a waterfront office, a master suite surrounded by glass, a living room, and a casual family room with wet bar.

The property

Outside the luxurious interior, exterior features on the 9,076 square foot lot are just as impressive: on the patio is outdoor bar. There's also a swimming pool, spa, outdoor shower, and bath.

And for those who'd rather sail under the Golden Gate Bridge than sit in traffic on top of it, the dock-- featuring, 12,000 lb. boat lift and an electric ramp--awaits.

The deal

In an area where the median list price is 3.89 million and $1,050 per square foot, multi-million dollar homes don't raise too many eyebrows. But this home, at $16 million and $3,805 per square foot might.

But then you remember this is a custom basically floating on Belvedere Island with its own private dock. And then $16 million seems just about right.
